Project 5

For a 10 cell series, calculate the voltage, current and SOC. Also simulate the aging and thermal effects at different charge and discharge rates. Comment on the battery pack’s capacity:

Battery Series connection:

In Series connection battery have connected Positive and Negative terminals have connected together.

Battery Pack capacity:

Here i have connected 10 Cell in series connection

For one battery have rated capcity is 5.4 Ah, So total 10*5.4.=54Ah

Total battery pack capacity is 54Ah

Power=Voltage*Current

Voltage is 7.2*10=72V

Power= 54*72

Power = 3888 kWh

Power= 3.8W

Charge and Discharge Rates:

Charge and discharge is 1C

Simulink Model & Results:

Here i have attached simulink model snap. Connected 10 cell in series connection and connecting current and voltage measurement block to find out the voltage and current of whole battery pack. Input load have connected and given 54 Ah current have input. Battery SOC subsyterm also attached to find the battery soc level.

RESULTS:

Here i have mentioned the results. Simulation run time is 3600 Sec

Aging and thermal effects:

Here i have attached simulink model and given temperature is 25

Results:

Simulation run time is 3600 Sec

Here i have attached the simulink models.
